Salt batteries match UPS and seasonal battery requirements
UPS batteries are gaining popularity. In the past, UPS was used mainly in hospitals, server rooms, mobile network base stations. These days, a growing number of businesses and even private houses consider installing UPS batteries in order to keep the lights on. Moreover, many businesses and homes are looking for a new battery type; the "seasonal battery". The idea of this battery type is to be charged up in summer, and it then provides electricity during winter months, when grid capacity is scarce. The UPS and seasonal batteries are large installations, and their requirements differ from ordinary mobile phone or electric car batteries.
While, UPS and seasonal batteries do not need long cycle life, they do need VERY long calendar life, measured in decades. Their owners want to be sure that once installed, these batteries will reliably serve through many years.
Secondly, these batteries need to be cost optimized, to make large installations affordable.
Thirdly, these batteries need to support a wide operating temperature range as they may be installed in rooftops or containers without air conditioning.
BroadBit Batteries' sodium-salt battery technology uniquely meets these requirements of UPS and seasonal batteries. Our sodium-salt battery includes only widely available materials, and is based on similar manufacturing technique to lead-acid batteries, which are the most cost-effective today. In other words: low-cost materials combine with low-cost manufacturing. Our SO2 solvent based electrolyte is known to provide multi-decade calendar life. These sodium-salt batteries operate in the -20 to +60 Celsius temperature range.
BroadBit is a technology company developing revolutionary new batteries using novel sodium-based chemistries to power the future green economy. We have already made high performance lab samples and are now commercializing the technology for next generation grid energy storage.
The batteries are based on metallic sodium and other widely available and plentiful compounds. Our main active material is a sodium salt. BroadBit is also developing a Li-ion battery electrolyte that extends battery cycle life.
